Authorities on Thursday were still searching for the Lafayette man accused of killing his 26-year-old girlfriend this past weekend.

Miles Joseph Guidry, 28, is wanted on a count of second-degree murder in the death of Claire Walley. Her body was found Sunday morning inside a home in Duson, along with the couple’s unharmed infant.

The University of Louisiana at Lafayette graduate student, who was pursuing a master’s degree in psychology, was buried Thursday in Lafayette.

Capt. John Babin, Lafayette Parish Sheriff’s Office spokesman, said investigators were diligently working to locate Guidry.

“They’re working hard. There’s just nothing new out there to report,” Babin said.

The circumstances surrounding Walley’s death are unclear.

Authorities are keeping the details about how she died confidential. Babin said publication of the specifics in the case could sway the suspect’s story once he’s found and interrogated.

“We have to be very careful about what type of information we put out,” Babin said.

The Lafayette Parish Coroner’s Office on Tuesday performed an autopsy on Walley and confirmed her death as a homicide. That office, too, didn’t release any further information.

Guidry was due in court on Thursday for a hearing on unrelated charges of simple criminal damage to property, illegal discharge of a firearm and aggravated flight from an officer.

In that case, Guidry is accused of crashing his car into the now-demolished Lafayette Habitat for Humanity building on Johnston Street in April 2014. After the crash, he allegedly shot a .357 revolver into the air and fled from a Lafayette police officer, according to court records.
